Annotation Type GridLocalNodeIdResource

@Documented
@Retention(value=RUNTIME)
@Target(value={METHOD,FIELD})
public @interface GridLocalNodeIdResource

Annotates a field or a setter method for injection of local node UUID resource. Node UUID is a globally unique node identifier and is provided to grid via GridConfiguration.

Local node ID can be injected into instances of following classes:

• GridComputeTask
• GridComputeJob
• GridSpi
• GridLifecycleBean
• @GridUserResource

Here is how injection would typically happen:

 public class MyGridJob implements GridComputeJob {
      ...
      @GridLocalNodeIdResource
      private UUID nodeId;
      ...
  }
 

or

 public class MyGridJob implements GridComputeJob {
     ...
     private UUID nodeId;
     ...
     @GridLocalNodeIdResource
     public void setLocalNodeId(UUID nodeId) {
          this.nodeId = nodeId;
     }
     ...
 }
